* FS Summary Counters
* ===================
*
* We correct errors in the filesystem summary counters by setting them to the
* values computed during the obligatory scrub phase. However, we must be
* careful not to allow any other thread to change the counters while we're
* computing and setting new values. To achieve this, we freeze the
* filesystem for the whole operation if the REPAIR flag is set. The checking
* function is stricter when we've frozen the fs.
